Answer:
(2,-9)
Step-by-step explanation:
Set the quadratic equal to zero.

Factor

Set each of these factors to zero

and


and

Plot the midpoint of the two values.

So the middle term is 2 and the other terms are 5 and -1.
Now the vertex is

So the vertex is
(2,-9)
Answer:
put x and y value in equation 1
3 (5+2)
3 (7)
21
Step-by-step explanation:
1) y = (3/8)x + (1/8)
2) y = -0.73x - 1.36 (rounded to nearest hundredth)
3) y = 4x + 15
4) y = (3/4)x - (13/2)
5) y = 3x + 5
6) y = -2x - 4
